Austrian made Piatnik cards are renowned for their quality; they're not 100% plastic, but they feel amazing. The first time I ever played with Piatnik cards I wondered why we weren't carrying them.
These cards show details of past and modern masters from Leonardo da Vinci to Claude Monet. The back of each card is illustrated with Jan Brueghel's "Vase of Flowers". They are beautiful cards that also teach artwork.
